It has a merge function that works great, just redefining CC, LD and AR in
makefile. I also managed with the CIL-lists help to make a visitor to make all
global declarations static which I needed for Renderscript. So far I have
managed to merge the libc string operations and a malloc implementation, as
well as making libx264 compile inside renderscript (have not had a chance to
test it yet).
